Y560p with latest BIOS, HDMI output: noise/ant

[Ferhat]

I have purchased my Y560p in the last month. The laptop's screen had lots of problems.. After searching forums i found out that the BIOS update may fix it, it fixed it, or at least hide it. But now i am also using my laptop with 24 inch samsung led screen. It's very obvious that especiall on the dark colors, i see lots of noise, anty screen. I don't know how to describe, it's like the old televisions.

Is this a problem that can be solved by software? Or should i change my laptop with another model? In forums i see that many other people are having this problem. Is a fix on the way?

hi ferhat,

guessing you are not having any issue at the main screen (now) so it could be hdmi cable or drivers issue. if it's possible, make sure the cable works properly and try to update the drivers from the link below.

hope this helps.

Thank you for your response. I've installed almost every single file from the page you've suggested, but the problem stays still. I've tried the same hdmi cable on my 2 other computers and 1 led tv, they did work fine. I also tried to switch hdmi cable but nothing changed.

guessing you are using nvidia graphic card. have you tried to update it from nvidia.com directly?

[Ferhat]

Yes i have the latest display drivers and software from the nvidia site.

By the way,

Eventhough my problem still continues,

By selecting "RGB 4:4:4 Pixel Format PC Standard (Full RGB)" instead of "YCbCr 4:4:4" (which was default) from the Catalyst Control Center>My Digital Flat-Panels>Pixel Format>Color Pixel Format", noise is less visible but it's still there.

Time to share with the community..

TODO list for everyone (as the solution) who has this problem:

1- Update BIOS

2- Update Windows

3- Update Graphics drivers from ati.amd.com

4- UPDATE LED SCREEN'S FIRMWARE (mine was samsung and yes there is such a thing)

5- Select "RGB 4:4:4 Pixel Format PC Standard (Full RGB)" instead of "YCbCr 4:4:4" (which was default) from the Catalyst Control Center>My Digital Flat-Panels>Pixel Format>Color Pixel Format".

You will almost see no visual disturbances and your problem will be solved.
